IMPROVED APPARATUS FOR EVAPORATING- BRINH AND OI'HER LIQUIDS.

The Schedule referred to in these Letters Patent and making part of the same.

' which 1 call a salt-evaporator; and I do hereby declare that the following is a full, clear, and exact descri 'ition of the construction and operation of the same, reference being had to the annexed drawin'gs, making a part of thisspecification, in which Figure 1 is a front view, showing the front elevation of the boiler, pan, and brick-work complete.

Figure 2 is a longitudinal view, showing or 1epre-' senting the side elevation all complete, only cut in the middle, to suit the proper size for the Patent Office.

Figure 3 is a longitudinal section through the line a, showing the interior of the boiler, evaporating-pan, steam-s uice, and flue underneath the steam-space, thereby superl'ieating the steam, and causing a rapid eva mration in pan.

Figure 4 is a top view of thepan, also cut in the middle, and showing the chimney.

Figure 5 is a section through the line B, showing or representing an end .view of the interior of the boiler,

stomp-space, and pan; also a continuation of the flue below the steam-space, into which the heated air from the sides of the boiler will rise, thereby preventing the condensation of the steam in the steam-spaceby the" action of the water in the pan.

1 will now proceed to describe steam-boiler, with strain-gauges, saletywalves, and water-gauges, and

force-pump.

The boiler is six feet two inches wide, and fourteen eet six inches long, or of any length or width to suit the flow: of brine.

A pan is attached to the steam-boiler, of boiler-plate, to hold the saline water, eighteen feet wide, makiiiga pan, over all, one hun red feet long and eighteen feet Wide, or of any length or breadth to suit the flow of brine. This pan is attached to the boiler, and has a steam-space about four inches The steam flows along the whole length and breadth of the pan. 7

The fire from the furnace, after passing through the "tubes of the boiler, passes through under the pan, also the heated air, thereby superheating the steam in-the steam-space, and causing a rapid evaporation of the saline water in the pan. 0

- I do not wish to confine the uses of my device to the evaporation of brine only, for I find it eminently useful in the evaporation of sorghum-juice, maple-sap, and other fluids.

' I prefer to place the boiler, as shown on the drawings, contiguous to the pan, but it may also be adjusted at a distance from said pan greater than the drawings represent.

What I claim as my invention, is- 1. The combination of an evaporating-pan with a steam-space beneath it, and fines adjusted to heat the steam-space by heat from the boiler-furnace,

2. The combination of an evaporating-pan with a steam-generator and superheater, substantially as specified.
